boringssl submodule in crates.io is incomplete

[WesleyRosenblum]

I'm trying to compile a project that has a Cargo.toml dependency on quiche on a 32-bit platform and I'm encountering this error:

CMake Error at /usr/local/share/cmake-3.23/Modules/CMakeDetermineSystem.cmake:130 (message):
    Could not find toolchain file:
    /cargo/registry/src/index.crates.io-1949cf8c6b5b557f/quiche-0.24.4/deps/boringssl/src/util/32-bit-toolchain.cmake

The quiche dependency is specified in my Cargo.toml as follows:

[dev-dependencies]
quiche = "0.24"

My understanding is that Rust crates published to crates.io include git submodules in the source as a regular directory. The boringssl submodule does appear in the source aquired from crates.io, but it is missing the referenced 32-bit-toolchain.cmake file:

curl -L 'https://crates.io/api/v1/crates/quiche/0.24.4/download' | tar -zxf -

ls -a quiche-0.24.4/deps/boringssl/src/util
.         ..        ar        fipstools

cat quiche-0.24.4/deps/boringssl/src/util/32-bit-toolchain.cmake
cat: quiche-0.24.4/deps/boringssl/src/util/32-bit-toolchain.cmake: No such file or directory

I believe this can happen if the git submodule hasn't been properly initialized or checked out at the time the crate was published to crates.io.

Thanks for the report Wesley. I wonder if this is another thing that will be fixed by #2080

Probably, but I think it would be a quick fix to do a cargo publish with the complete submodule in place

Hi @LPardue,

Can we get some updates on this issue? Thanks :)
